Create a copy of the project in Expression Blend with a different name

Question

Microsoft

Colleagues, help solve the issue. There is a prototype created in expression blend/ There was a need to create several copies of this project with different names.
I go to file, save a copy of the project as. At this point, everything is fine, a new solution with a new name is created in the specified folder. But here's the problem! The names of the projects in the solution remain the same and, accordingly, when I do “pack the project” after launching in the browser, the name of the original project is written on the tab and not the new one.
Actually, the question is how to rename the project (I emphasize that it is the project that is part of the solution)?
ps Thanks in advance to all who responded, sorry, but I won’t put pluses, it’s still small.
